Apparently Ri-Ri left her pants behind on the last stop, because when the "Diamonds" singer took the stage in Berlin, she was wearing a tee with a pot leaf on it, some thigh-high boots, a jacket and, ummm, that's about it.

Oh, right, there were also sunglasses. Cat-eye ones. Very on trend. But no pants. And, in case you're wondering where she left those pants, we know this: They aren't in Stockholm.
